MKF / MKFT (E5) 06/2020 page 30/176
To completely separate the chamber from the power supply, you must disconnect the power plug. Install
the chamber in a way that the power plug is easily accessible and can be easily pulled in case of danger.
With an increased amount of dust in the ambient air, clean the condenser fan several times a year. We
recommend checking the fan grid (behind the left maintenance access flap) every week. In case of visible
dirt accumulation, disconnect the chamber and clean the fan grid by suction.
Avoid any conductive dust in the ambiance according to the chamber layout complying with pollution de-
gree 2 (IEC 61010-1).
MKF 56: With option “External freshwater and wastewater cans” (chap. 21.9): Install the chamber in a
way that the freshwater can is easily accessible for filling.
4. Installation and connections
4.1 Wastewater connection for humidifying system
Fasten the wastewater hose to the wastewater connection “OUT” (14) on the rear of the chamber (olive ∅
14 mm). Observe the following points:
• You can use a part of the supplied tap water hose as a drainage hose. In case another hose is used, it
has to be permanently resistant against at least 95 °C / 203 °F.
• Mount the wastewater hose with a maximum positive inclination of 1 m and a maximum total length of
3 m.
• Protect both ends of the drainage hose with two of the four supplied hose clamps.
Wastewater is collected in an internal can with a volume of approx. 0.5 liters. It is pumped off
only when required, thus there is no continuous wastewater flow.
Protect the wastewater supply at both sides with the supplied hose clamps.
4.2 Freshwater supply for humidifying system
Connect the wastewater pipe before connecting the chamber to a freshwater pipe or filling the
water can (internal water can: regular with MKF/MKFT 115, 240, 720, external water can: op-
tional for MKF 56).
MKF 56: You can supply the chamber with freshwater via a water pipe or by manually filling an external
water can (option chap. 21.9).
MKF/MKFT 115, 240, 720: You can supply the chamber with freshwater via a water pipe or by manually
filling the internal water can. It is not necessary to switch between both possibilities. When connecting to
a water pipe, the water can is automatically filled.
Water intake temperature NOT below +5 °C / 41 °F and not exceeding 40 °C / 104 °F.
NOTICE
Danger of calcification of the humidifying system.
Damage to the chamber.
Operate the chamber with deionized (demineralized) water only.
